SPRING-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 496,722, dated May 2,1893.

Application filed October 1, 1892.

To all whom it may concern:

Be it known that I, EDWARD CLIFF, of Newark, in the county of Essex, inthe State of New Jersey, have invented new and useful Improvements inSpring-Setting Machines, of which the following, taken in connectionwith the accompanying drawings, is a full, clear, and exact description.

In the manufacture of helical springs they are usually of excessiveheight when taken from the mandrel upon which they are wound and formed.

The purpose of this invention is to compress and set said springs to therequired normal heights. And to that end the invention consists in theimproved construction and combination of the component parts of thespring setting machine hereinafter fully described and set forth in theclaims.

In the accompanying drawings Figure 1 is a side elevation of a machineembodying my invention. Fig. 2 is an end elevation of the same. Fig. 3is a vertical transverse section on line as, 00, in Fig. 1. Fig. 4 is aplan view of the machine. Fig. 5 is a vertical transverse section online y, y, in Fig. 4, and Fig. 6 is a vertical longitudinal section online 2, 2,. in Fig. 4..

Similar letters of reference indicate corresponding parts.

A- represents a horizontally elongated stout frame consistingessentially of two sideplates firmly secured at one end to oppositesides of the standard A'-=- and at the opposite end to a transverseplate A. Said side-plates are thus sustained a proper distance apart toaccommodate between them the gears, pinions, &c., hereinafter described.The standard -A'- is formed with the passage -B extending horizontallythrough it, and in said passage is seated the plunger F. Across theopposite end of the frame -A- is the main driving shaft 0tjournaled inbearings in the side-plates of the frame and having secured to one orboth ends the drivin g pulley or pulleys O and balance-wheel or wheelsO. Between the aforesaid sideplates are pinions N--N- fastened to theshaft a and meshing with large gearwheels N'N attached to acounter-shaft -a which is parallel with the main shaft --aand mounted insuitable bearings in Serial No. 447,467. (No model.)

the side plates of the frame. On the countershaft is also secured aneccentric -e to which is connected the pitman --L- by the usualeccentric strap. The opposite end of said pitman is connected to theplunger -F which thereby receives a reciprocating motion, the speed ofwhich is considerably reduced by the large gear-wheels N'-N'transmitting motion from the small pinions -NN to the counter shaft -a'.

Opposite the plunger is the abutment C a proper distance therefrom toreceive be-- tween them the helical spring swhich is to be disposedaxially parallel with the plunger and receive from opposite ends thepressure of the plunger and the abutment. This abutment I prefer tocushion by means of a suitable spring the resistance of which is 'adjustable so as to guard against excessive pressure of the plunger. Forthis purpose I mount the abutment longitudinally movable in a recess R-formed in a standard --P. The abutment O- is formed with a cavity --C'-in the end farthest from the plunger, and in said cavity is seated" astout helical spring D-- which bears with its opposite ends against therear or inner side of the abutment and against the opposite end-wall ofthe recess,R. Thiswallis formedwithanutI- which is axially in line withthe aforesaid cavity, and through said nut passes a screw -S-, the innerend of which is connected to the abutment -C-=- preferably by a swivelwhich allows the screw to turn freely on the abutment. By turning thesaid screw the abutment is caused to move longitudinally to compress thespring D to a greater or less degree and thus impart the desired degreeof resistance to the abutment.

To facilitate the operation of feeding to the testing machine thesprings to be tested,Iinterpose between the abutment -O and plunger -F,a vertically revoluble holder b provided in its periphery with a seriesof recessed seats -b-b= for the reception of the springs to be set. formof a wheel mounted 011 a shaft parallel with the axis of the plunger.The periphery of which wheel is, formed with the recesses -b--bin whichthe helical springs -sare laid horizontally. Said wheel is to be turnedintermittently to carry the springs Said holder is of the successivelyto a proper position between the abutment and plunger to receive thetesting pressure therefrom. In the subsequent movement of the revolubleholder or wheel b, the tested spring drops automatically therefrom. Iprefer to cause the said wheel to turn automatically and for thatpurpose I fasten to the sides of the shaft -b of said wheel two sets oftappets cc disposed diagonally on the shaft, and to the plunger F Iattach a rod dwhich is parallel with the aforesaid shaft and has affixedto it a wing f. The rod dreciprocating with the plunger engagesalternately one of the tappets of each set and thereby causes the shaftb" to turn intermittently. To further facilitate the feeding of thesprings to the machine I employ a trough or way twhich is inclined tothe wheel or holder -13- and guides the springs which roll by gravity tothe said holder and drop into the recesses Z) thereof.

Having described my invention, What I claim as new,and desire to secureby Letters Patent, is-

1. In combination with the abutment and v plunger, a revoluble holderfor the springs to be set interposed between said abutment and shaft andmeshing with the aforesaid pinions,

the eccentric eon the same counter shaft, the pitman L connecting theeccentric with the plunger, the standard P opposite said plunger, andthe spring-cushioned abutment C in said standard, substantially asdescribed and shown.

In testimony whereof I have hereunto signed my name this 20th day ofSeptember, 1892.
